Developing Advanced Patient-Specific In Silico Models: A New Era in Biomechanical Analysis of Tooth Autotransplantation.

Introduction: As personalized medicine advances, there is an escalating need for sophisticated tools to understand complex biomechanical phenomena in clinical research. Recognizing a significant gap, this study pioneers the development of patient-specific in silico models for tooth autotransplantation (TAT), setting a new standard for predictive accuracy and reliability in evaluating TAT outcomes.

Methods: Development of the models relied on 6 consecutive cases of young patients (mean age 11.

Liarozole fumarate inhibits the metabolism of 4-keto-all-trans-retinoic acid.

The metabolism of 4-keto-all-trans-retinoic-acid (4-keto-RA), a biologically active oxygenated metabolite of all-trans-retinoic (RA), has been examined. In vitro, incubation of [14C]4-keto-RA with hamster liver microsomes in the presence of NADPH produced two major radioactive metabolites which were more polar than the parent compound. Following isolation, appropriate derivatization and analysis by GC-MS, these compounds were tentatively identified as 2-hydroxy- and 3-hydroxy-4-ketoretinoic acid.

The metabolism and excretion of risperidone after oral administration in rats and dogs.

The metabolism and excretion of risperidone (RIS; 3-[2-[4-(6-fluoro-1,2-benzisoxazole-3-yl)-1-piperidinyl]ethyl]-6,7,8,9- tetrahydro-2-methyl-4H-pyrido[1,2-a]pyrimidin-4-one), a novel antipsychotic drug, were studied after single po administration of radiolabeled RIS to rats and dogs. In rats, the excretion of the radioactivity was very rapid. The predominant excretion in rat feces (78-82% of the dose) was related to an extensive biliary excretion of metabolites (72-79% of the dose), only a small part of which underwent enterohepatic circulation.

Comparative metabolism of flunarizine in rats, dogs and man: an in vitro study with subcellular liver fractions and isolated hepatocytes.

1. The biotransformation of 3H-flunarizine ((E)-1-[bis(4-fluorophenyl)methyl]-4-(3-phenyl-2-propenyl)piperazine dihydrochloride, FLUN) was studied in subcellular liver fractions (microsomes and 12,000 g fraction) and in suspensions or primary cell cultures of isolated hepatocytes of rats, dogs and man. The major in vitro metabolites were characterized by h.
